EDWARD DIETRICH, OF HENRYVLLE, INDIANA.

To all whom t may cof/wem.'

Be it known that I, EDWARD. DIETRICH, a citizen of the United States, residing at -Henryville, in the county of Clark and State ofl Indiana, have invented certain new and 'useful Improvements in Socket- Wrenches, of which the following is a specication. l

This. invention relates to socket wrenches, and it comprises a casing, a pair of p-awls mountedtherein, a socket mounted to revolve in ksaidcasing, said socket being providedwith ratchet teeth, adapted to be engaged by said pawls, an operating handlepivotally` vmounted in the casing and projecting therefrom:

'In the present invention, I have provided a `wrench particularly adapted for use on motor vehicles and in other work where the clearance spaceis restricted and the user of the wrench is likely to become in]ured when employing an ordinary wrench if the wrenchi slips. p

In the present construction, a socket member isprovided which is adapted to receive the nut or the head of the bolt, and ythis member isrevolved through the medium of a pair of pawls or dogs engaging ratchet l teeth formed on the periphery of the socket member.

One of the dogs is arranged to pull on the ratchet teeth and the other to push, the dogs being operated by a pivoted operating handle or lever which extends out` wardly from the casing and may be operated at considerable distance away where suilicient clearance can be obtained.

The easing comprises a pair of sections adapted to be secured to each other, having peripheral flanges engaging each'other.v A portion of the face of each section 'of the casing is depressed, forming guides between the depressed portion and the outer flange for the reception of the dogs.

In the accompanying drawings, I have shown one embodiment of the invention. In

this showing:

Application filed March 28, 1921. Serial' No. 456,427. I

Fig. 3 is a transverse vertical sectional view on line 3 3 of Fig. 1,

Fig. 4l is a similar view on line 4 4 of Fig. 1, and, f

`Fig. 5 is a sideelevation of a portion `of the casing showing the position of the operating member. r

`Referring to the drawings, the reference numeral 1 designates the casing as a whole. As shown, it is formed of two similar sections, being split longitudinallyV of the wrench;V Each of the sections is` provided withr a peripheral iange 2,whereby the faces Bare slightly spacedv from each other. The center portion of each section ofthe casing is depressed, as at el, in a plane substantially parallel withy the outer edges of the periphrpressure when the dog is moved toward theff head of the wrench, and the other dog is provided with a tooth 12 adapted to exert a pressure when the dog is moved in the opposite direction. The dogs are connected by a coil spring 13, normallytending to draw them toward each other.

The head of the wrench'is provided with a pair of openings 14, arranged in the faces 3 of the casing and in alinement with each other. A socket member 15 is adapted to be arranged in this opening, the socket member being provided with a hub 16, adapted to be received between the faces of the cas-y ing to retain it in position to form a bearing therefor. As shown, this head is provided with ratchet teeth 17, adapted to be engaged by the teeth 11 and 12 of the pawls. A spring catch 18 is mounted on one of the bolts or yrivets 7 and is adapted to engage one of the ratchet teeth to prevent the socket from turning in a reverse direction. Adjacent the opposite end of the casing, the

I 9 and 10 are secured to the operating lever by suitable means, as at 22 and 23. The

youter end of the operating lever is provided with a socket 24- for the reception of a handle which may be made of any suitable;

length. y

-In operation, the operating lever 211 is oseillated by the handle, to reciprocate the dogs 9 and 10 in the guidevvays 6. The dog 9, When moving forwardly, engages the ratchet 17 to turn the socket 15, and the dog 10, when moving in the opposite direction, causes the socket to revolve. The spring 13 maintains the dogs in engagement With the Vsocket at all times, and the socket is prevented from revolving in a reverse direction by means of the spring catch 18. The length of the slot 19 isbest made suflicient to cause the dog to revolve the socket a distance equal to one of the ratchet teeth upon each oscillation ofthe lever 24. It Will be apparent that ythe operating handle 25 may be made any suitable length and the operator may use the Wrench in places Where very little clearance is afforded, as when Working on motor vehicles and operatefthe wrench from a place Where suiiicient clearance is provided, by means of the handle 25. By providing the Socket 24 in the end ofthe operating lever, the handle 25 may be removed When the Wrench is not in use to facilitate transportation. s

It is to be understood that the form of f the yinvention herewith shown and described is toy betaken as a preferred example of the same, and that various changes in the shape,

size, and arrangement of parts may be ref sorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A socket Wrench comprising an outer casing, said casing being formed of two sections provided With peripheral flanges engaging each other to space the sides of the ,Casing from each other, said casing being4 provided with a centrally depressed portion forming a pair of guideways, a dog arranged in each of' said guideways, a socket mounted to revolve in the casing, said socket being provided With ratchet teeth adapted to be engaged by said dogs, and an operating lever pivotally mounted inrsaid casing and connected to'said' dogs. i y2. A socket Wrench comprising anv outer casing, 'said outer casing comprising a pair of plates having peripheral flangesl forming the sides of the casing and maintaining the facesfspaced from each other, the faces of the casing being provided with Vcentrally disposedv depressed portions forming f a guideivay at each side of the casing, a dog mounted to reciprocate in each of said guidey Wavs, a socket mountedto revolve in said casing, said socket being provided With ratchet teeth adapted to beengaged by said clogs, an operating handle pivotally mounted in said casing adjacent the oppositeends'of said dogs, and means for connecting said dogs to said handle, said casing lbeing provided With a slot in one side through which the operating handle projects.v

1n testimony whereof I aiiiX my signature in presence of twofwitnesses.
